asp.net - Stream.WriteAsync throws The remote host closed the connection exception -

i have asp.net webforms application , retrieve video database saved in varbinary format , show html5 video tag.

after googled it, found way should play asynchronously using asp.net webapi, works fine

first problem

when video played first time , user click on play button replay video, the remote host closed connection. error code 0x800704cd exception throws @ line await outputstream.writeasync(buffer, 0, bytesread);.

second problem

when user click on seek bar, video goes played first.

note

internet explorer 11 plays video without problem, firefox , chrome have both problems.

how can solve problem?

here codes:

public static class webapiconfig {     public static void register(httpconfiguration config)     {         config.enablecors();          config.maphttpattributeroutes();          config.routes.maphttproute(             name: "videoapi",             routetemplate: "api/{controller}/{id}",             defaults: new { id = routeparameter.optional }         );     } }  public class videocontroller : apicontroller {     public ivideorepository videorepository;      public httpresponsemessage get(long id)     {         try         {             videorepository = new videorepository();             video video = videorepository.load(id);              if (video != null)             {                 var videostream = new videostream(video.filecontent);                 string ext = video.extension;                  var response = request.createresponse();                  response.content = new pushstreamcontent((action<stream, httpcontent, transportcontext>)videostream.writetostream, new mediatypeheadervalue("video/" + ext));                  response.content.headers.add("content-disposition", "attachment;filename=" + video.fullname.replace(" ", ""));                 response.content.headers.add("content-length", videostream.filelength.tostring());                  return response;             }             else             {                 return request.createresponse(httpstatuscode.notfound);             }         }         catch (exception e)         {             return request.createerrorresponse(httpstatuscode.serviceunavailable, e);         }     } }  public class videostream {     private readonly byte[] _filecontent;     private long _contentlength;      public long filelength     {         { return _contentlength; }     }      public videostream(byte[] content)     {         _contentlength = content.length;         _filecontent = content;     }      public async void writetostream(stream outputstream, httpcontent content, transportcontext context)     {         try         {             var buffer = new byte[65536];              memorystream memorystream = new memorystream();             memorystream.write(_filecontent, 0, _filecontent.length);             memorystream.position = 0;             using (memorystream)             {                 var length = (int)memorystream.length;                 var bytesread = 1;                  while (length > 0 && bytesread > 0)                 {                     bytesread = memorystream.read(buffer, 0, math.min(length, buffer.length));                     await outputstream.writeasync(buffer, 0, bytesread);                     length -= bytesread;                 }             }         }         catch (exception e)         {             throw e;         }                 {             outputstream.close();         }     } } 

update

after way didn't worked properly, had use this way, new way have seekbar problem, when user click on seek bar seek time dosn't work in chrome , firefox.

asp.net not @ video streaming. third-party video streaming solution best option.

there few video-streaming servers (like wowza), require installation , have buy license.

cloud streaming service option. prefer aws cloudfront. propose distribution in various globally distributed content delivery zones. costs cheap , can sure survive traffic amount (even if users watch same video simultaneously).
